Chemical Structure
Description
The molecular framework of 4,7-Bis(5-bromo-4-n-octyl-2-thienyl)-2,1,3-benzothiadiazole (C30H38Br2N2S3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
